This one comes from episode 14 of season 2 called “A Clone of my Own” where Hubert Farnsworth reflects on his life during his birthday. This leads him to make a clone as a successor who ultimately doesn’t want to be a scientist like Hubert. He then is taken to the Near Death Star where retirees are put into pods and live in virtual reality. Eventually he’s rescued by the Planet Express crew that now contains his close, Cubert. During his life long reflections, we see that Hubert was an avid Dungeons & Dragons player (surprise surprise) so I thought this was a simple design to replicate.

Here’s the link to the product as a pim, but you can view the design on multiple items if you’re interested.
